Data analysis was performed using advanced statistical methods, including correlation analysis and Cox proportional hazards models, focusing on the critical factors that may influence survival.
Clinical and Demographic Characteristics of the Patients
The study included 133 patients, of whom 57.1% were female, with a median age at diagnosis of 64 years. Interestingly, 52.6% of the patients were diagnosed with bone metastases at the same time as the DTC diagnosis. The most common type was follicular thyroid cancer, with the study noting that the presence of lymph node metastases was common among 40.6% of patients. Metastases in other locations, such as the lungs, were present in approximately 60.9% of cases. The most common site for bone metastases was the spine, reported in 63.2% of cases.
Treatments and Clinical Trials
The treatments used in patients with bone metastases include a range of options such as radioactive iodine treatment (I131) and multi-kinase inhibitors (TKIs). About 90.2% of patients received radioactive iodine treatment, with 68.4% of them showing a positive response to the treatment. Targeted therapies and radiation interventions were also provided as needed. Nevertheless, a number of patients faced side effects involving issues like bone-related events such as fractures and pressure on the spinal cord, highlighting the need for effective interventions to alleviate symptoms and improve quality of life.
Study Results and Statistical Analysis
The study results showed that the survival rate of patients after 5 years was 39.5%, while it declined to 28.5% after 10 years. The presence of lymph node metastases, receiving radioactive iodine treatment, and being older than 67 years were key factors associated with negative outcomes. These results provide compelling evidence of the need for close monitoring and management of factors affecting survival.
Factors
Prognosis and Its Impact on Treatment
Several factors are associated with survival rates in patients with bone metastases from DTC. The presence of lymph node metastases is one of the important factors in determining therapeutic outcomes.

Radiation Therapy for Brain Metastases Resulting from Thyroid Cancer
Radiation therapy is one of the common treatments used in patients with brain metastases (BM) resulting from differentiated thyroid cancer (DTC), with studies showing that 64.7% of patients underwent this type of treatment. It has been observed that despite the frequency of radiation therapy use, there were no clear differences between patients who received radiation therapy and those who did not in terms of lymph node involvement, T stage, presence of multiple metastatic sites, pulmonary metastases, or recurrent metastases. Age differences were evident, with the average age of patients receiving treatment being 65 years compared to 71 years among those who did not receive treatment. This indicates that elderly patients may be more susceptible to the negative effects of brain metastases, necessitating careful consideration in customizing treatment based on each patient’s overall health status.
Factors Influencing Treatment and Side Effects
In addition to radiation therapy, a significant proportion of patients, 42.1%, received targeted drug therapy known as TKIs, such as sorafenib and lenvatinib. Approximately 53.5% of these patients faced treatment-related complications, including side effects ranging from low calcium levels to severe anemia. For instance, some patients experienced serious complications such as kidney damage and hypertension. These data indicate that the use of TKIs is not entirely safe and requires close monitoring of patients. Additionally, anti-bone resorption therapy was administered to 31.8% of patients, with notable side effects including a rare case of osteonecrosis of the jaw.
Mortality Rate and Risk Factors for Death
Among the patients followed, 54.1% died during the follow-up period, with the primary cause of death linked to thyroid cancer according to records. For those who died due to DTC, influencing factors included age, which is a clear interconnected cause of the increased risk of mortality in these patients. Additionally, the presence of lymphatic metastases and reduced mobility as a result of spinal cord compression had a significant impact on mortality risk. According to multivariable analyses, factors associated with increased risk included age over 67 years and the presence of lymphatic metastases, reflecting the importance of managing these factors to enhance patient care and provide the most effective treatment options.
Survival Analysis
The survival analysis for patients with brain metastases attempted to determine how long patients survived after diagnosis. The results revealed that the survival rate after 3 years was 53.5%, while this rate dropped to 39.5% after 5 years and 28.5% after 10 years. This gradual decline highlights the challenges faced by patients following the diagnosis of brain metastases. It is worth noting that the differences in survival were associated with specific diseases such as type of treatment, as radiation therapy had a protective effect on patients compared to those who did not receive it. These data require adopting a strategy characterized by personalization and a deep understanding of the disease’s aspects and their impact on treatment outcomes.
